Question

a scale drawing of a school bus has a scale of 1/2 in to 5 ft. if the length of the school bus is four and a half inches on the scale drawing, what is the actual length of the bus?​

Answer 1

45 feet

Explanation:

Set up Ratios

1/2 in/5 ft = 4 1/2 in/x

Solve for x by cross-multiplying:

`(1/2)/(5)` times
`(4 1/2)/(x)`

4 1/2 times 5 = 22 1/2

1/2 times x = 1/2x

22 1/2 = 1/2x

45 = X

Therefore the actual length of the bus is 45 feet.

Hope it helps :)
